What is a Platypelloid pelvis?
Platypelloid. The platypelloid pelvis is also called a flat pelvis. This is the least common type. It’s wide but shallow, and it resembles an egg or oval lying on its side.
What is a Gynaecoid pelvis?
Gynecoid pelvis: The gynecoid pelvis is one that is generally characteristic of a woman in its bone structure and therefore its shape. Gynecoid means like a woman, womanly, female. The gynecoid pelvis is more delicate, wider than, and not as high as the male pelvis. The angle of the female pubic arch is wide and round.
What are the four types of pelvis?
Although pelvises can be classified according to diameter, in obstetric practice they are often divided into 4 main types: gynecoid, android, anthropoid, and platypelloid, based mainly on the shape of the pelvic inlet [5].
What are the 3 pelvic bones?
In discussing the pelvis, a distinction can be made between the “pelvic spine” and the “pelvic girdle.” The pelvic girdle, also known as the os coxae, Latin for “bone of the hip,” consists of the fused bones identified individually as the ilium, ischium, and pubis.
What is the true and false pelvis?
The true pelvis contains the pelvic colon, rectum, bladder, and some of the reproductive organs. The false pelvis supports the intestines (specifically, the ileum and sigmoid colon) and transmits part of their weight to the anterior wall of the abdomen.
What is an anthropoid pelvis?
An apelike pelvis with a long anteroposterior diameter and a narrow transverse diameter.
What is Rachitic pelvis?
A contracted and deformed pelvis, most commonly a flat pelvis, resulting from rachitic softening of the bones in early life.
What is the diameter of Gynaecoid pelvis?
The gynecoid pelvis was defined if all the 12 measured parameters were positive in the following: pelvic inlet (obstetric conjugate >10.5 cm, transverse diameter >13 cm, and posterior sagittal diameter >4.5 cm), midpelvis (plane of greatest diameter: anteroposterior diameter >12.5 cm, transverse diameter >12.5 cm, and …
How is Pelvimetry done?
Pelvimetry assesses the size of a woman’s pelvis aiming to predict whether she will be able to give birth vaginally or not. This can be done by clinical examination, or by conventional X‐rays, computerised tomography (CT) scanning, or magnetic resonance imaging (MRI).
What shape is the pelvis?
Anthropoid pelvises are oval-shaped—they’re oval at the inlet and roomy front to back. Then, there’s the heart-shaped or android pelvis (yep—just like the phone). About 25 percent of women have this type. Lastly, just 5 percent of women have a platypelloid pelvis, which is oval and has a wide pubic arch.
What is the pelvis bone called?
What is the pelvis? Sacrum. A spade-shaped bone that is formed by the fusion of 5 originally separate sacral vertebrae. Coccyx (also called the tail bone).
What is the function of pelvic?
The pelvis provides attachment for muscles that balance and support the trunk and move the legs, the hips, and the trunk.
Pelvic inflammatory disease (PID). PID is an infection that occurs in the female reproductive system.
What are the X ray views of the pelvis?
X-Ray Views. The routine pelvic view is anteroposterior (AP) projection, and in 94% of cases, a correct diagnosis can be made from this view. When the fracture is noted in the AP view, special views (inlet and outlet view and oblique views) for further investigations are recommended. Radiographic interpretation is systematized with ABCS approach:
What are the 3 parts of the pelvis?
The anterior superior iliac spine (ASIS) is located at the anterior end of the iliac crest.
What is the inferior portion of the pelvis?
The inferior hypogastric plexus is also known as the pelvic ganglion. Classic anatomical studies have provided few details of the inferior hypogastric plexus morphology or the location and nature of the associated nerves. The fusion of the pelvic splanchnic nerves, sacral splanchnic nerves, and superior hypogastric plexus along with visceral afferent fibers forms the inferior hypogastric plexus.
